Welding questions

not to hi jack, but has any of u guys ever used a mig w/ an alum spool gun on it? getting ready to try it out, and curious what other people have done w/ one.
welder is a 175 eastwood mig----------------thanks for any comments---bob:coffee2:
for alum a spool gun is the best way for sure .weldind alum is like soldering it has to be clean . when I weld used alum mostly on commercial boats I clean it with acid first wire wheel cleaner its called . try not to breath in many fumes if possible that **** is nasty
